Centerless Grinding Machines
|
Centerless grinding machines are used to grind or finish rolls, rollers, shafts, connecting rods, valve stems or other precision cylindrical or radially symmetric shapes that have a uniform cross-section not profiled along the length. With centerless grinding machine tools, cylindrical workpieces are placed between a grinding wheel and regulating wheels. The regulating wheels cause the workpiece to rotate, producing a precision cylindrical part. Parts are seated on a work rest instead of a center in order to provide faster and easier workpiece insertion and removal. Centerless grinding machines are primarily used in high production applications and include throughfeed and plunge grinding. Plunge grinding centerless machines are used to grind or finish spherical outer diameters, tapers, or other precision radially symmetric or cylindrical shapes where profile varies along the length. Products & Services
Grinders and grinding machines use an abrasive that is bonded to a wheel, belt or disc to remove material and improve surface finish.
